About this document

Enthalpy Changes in Chemical Reactions by Ronald Mcdonald is a document available to read on EtoBox.

1. Energy is absorbed when bonds are formed and released when they are broken. 2. The temperature of the aluminum sample increased from 25°C to 30°C. Using the specific heat capacity, the amount of heat energy added was calculated to be 2.3 J. 3. For the reaction MnO2(s) + C(s) → Mn(s) + CO2(g), the change in enthalpy ∆H was calculated to be -130 kJ.
